W5 intake pics

Was small and large runner designs for customization or different motorsports in general ?
Somewhere in there literature, they describe the smaller runner as a street intake. (AKA-street/strip)
The large runner is a track design.
2000 Mopar Performance catalog lists W5 intakes not sure how long after that the intakes were produced would you know ?
Thanks Chris
I used to know! LOL!
